Following up on my previous post, if you don't stopover, the systemwide will carry you thru all the way to either a stopover point or your final destination.
So, in Always Flyin's case, using a systemwide for the return SIN-HKG would mean that he will need another systemwide from HKG-LAX because he stayed in HKG for more than 24 hours. If he stayed less than 24 hours, he would be doing a layover in HKG and the systemwide he "used" in SIN would carry him all the way to LAX.
Hmm. Just realized that this thread is my 777 posting.
